Compound and Application Performance of the Plant-based Anti-UV Finishing Agent

The pure natural anti-UV finishing agent was extracted respectively from turmeric,Scutellaria and rhubarb by the method of water circumfluence.The compound experiments of anti-UV finishing agent were arranged according to uniform recipe design UM15(15(3))table,and the best compound program was obtained.The silk fabrics were treated by the compound solution and the UV transmittance,surface morphology,washability,air permeability,capillary effect,breaking strength and breaking elongation of the treated fabrics were measured.The results show that,the UV transmittance T(UVA) of the treated fabric after is 2.61%,T(UVB) is 2.62%,UPF is 41.62.The effect of anti-UV finishing agent is excellent, and the wearabilities of the fabric are not affected.
